A kind of optical cable insertion sealing device of crossing comprises central tube, sealing drum, some groups of black boies and eccentric flange; Described central tube is fixedly connected with described sealing drum, described eccentric flange, the supervisor hole eccentric setting of central tube, and described black box is arranged on outside sealing drum, to the sealing gap inserted between sealing device and patchhole; Described center tube wall is provided with cable installing hole, passes for cable, described cable installing hole is provided with hermetically-sealed construction.
Further, described central tube two ends arrange the screw thread and screwed hole that match respectively, make described insertion sealing device can cascade.
Further, the screw thread at described central tube two ends and screwed hole are NPT screw thread.
Further, described black box comprises joint ring group, spacer and lock sleeve; Described spacer is arranged between each group of joint ring group; Described sealing drum is provided with convex rank; Described lock sleeve is arranged on described sealing drum afterbody by screw thread, coordinates with the convex rank on sealing drum, is integrated by black box lock.
Further, wavy spring back-up ring is provided with between the described joint ring of described joint ring group.
Further, described central tube head and afterbody are provided with eccentric convex rank.
Further, the end on the convex rank of described bias is provided with guide surface, reduces the resistance in motion.
Further, the hermetically-sealed construction of described cable installing hole is NPT screwed hole.
The utility model achieves the function that test cable passes through, and the process embodiment for horizontal well hierarchical monitor provides the instrument of feasibility.

Detailed description of the invention
Below, with reference to accompanying drawing, the present invention is more fully illustrated, shown in the drawings of exemplary embodiment of the present invention.But the present invention can be presented as multiple multi-form, and should not be construed as the exemplary embodiment being confined to describe here.But, these embodiments are provided, thus make the present invention comprehensively with complete, and scope of the present invention is fully conveyed to those of ordinary skill in the art.
For ease of illustrating, here can use such as " on ", the space relative terms such as D score " left side " " right side ", for illustration of the element of shown in figure or the feature relation relative to another element or feature.It should be understood that except the orientation shown in figure, spatial terminology is intended to comprise device different azimuth in use or operation.Such as, if the device in figure is squeezed, be stated as the element being positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, exemplary term D score can comprise upper and lower both orientation.Device can otherwise be located (90-degree rotation or be positioned at other orientation), and space used here illustrates relatively can correspondingly explain.
Insert sealing device as shown in Figure 1, be made up of central tube 1, sealing drum 2, spacer 3, lock sleeve 4 and eccentric flange 5 and 4 groups of joint rings 6.
Central tube 1 and sealing drum 2, by being threaded, realize sealing by "O"-ring; Eccentric flange 5 is respectively arranged with the cable installing hole 8 and central tube installing hole that pass through for test cable; And be bolted on the convex rank of central tube 1 afterbody by 2; Sealing drum 2 is equipped with black box, through between oil reservoir during patchhole, patchhole is sealed.
As shown in Figure 2, central tube 1 adopts eccentric design, and its axle center is departed from the supervisor hole 7 of central tube 1, increases with the space of sealing drum 2 inwall, and thicker cable can be made by inserting sealing device.The head of central tube 1 and afterbody are provided with eccentric convex rank, and this structural rate adopts the scheme of through hole to alleviate the weight of part; The end on two convex rank of bias is provided with taper guiding face, can adopt other forms of guiding face, as arc surface etc. during concrete enforcement; Reduce the resistance of sealing device motion process.The convex rank of central tube head side have the cable installing hole 8 parallel with tube bore axis; Cable installing hole 8 wall has certain thickness, ensures the intensity of screw thread hole wall.The outside dimension value entering device under screwed hole and optical fiber or cable matches.Screwed hole is NPT screwed hole, is used for sealing cable installing hole 8.
Central tube 1 two ends arrange the screw thread and screwed hole that match respectively, make insertion sealing device can cascade; Conveniently seal, screwed hole is NPT screwed hole.
Sealing drum 2 being equipped with black box is 4 groups of (8) joint rings 6, is separated between every two groups of joint rings 6 by spacer 3; Lock sleeve 4 is same with sealing drum 2 by being threaded, and the convex rank on lock sleeve 4 and sealing drum 2 coordinate, for fixing seal ring 6 and spacer 3; This sealing means structure is simple and effectively can ensure the safety and reliability that seals.The group number of joint ring 6 is not limited to 4 groups, when specifically implementing, and can also select the group number of joint ring according to down-hole situation.The spacing of each group of joint ring 6 can be changed by changing spacer 3, adapting to the patchhole of different wall.Adopting is threaded also is convenient to the sealing state adjusting joint ring 6.
Isolate with wavy spring back-up ring between the joint ring 6 with group, the distortion of restriction joint ring 6, ensures sealing effectiveness.
Under enter device before, central tube 1 is arranged on sealing drum 2; Sealing is inserted at NPT screwed hole; Optical cable outer tube is passed from NPT screwed hole, then NPT is turned cutting ferrule metal seal and screw the sealing realizing two ends, cable passage; The cable installing hole 8 of cable outer tube from eccentric flange 5 is passed; Eccentric flange 5 is socketed on central tube 1, by bolt, eccentric flange 5 is fixed on central tube 1; Finally, sealing device is inserted with under other lamination test devices successively lower going-into-well.Enter under concrete insertion sealing device quantity and under enter position and lay according to concrete hierarchical monitor process program.
Example, just for illustration of the utility model, in addition, also has multiple different embodiment, and these embodiments to be all those skilled in the art can expect after comprehension the utility model thought, therefore, will not enumerate at this.
